lMPRQ-VE MENT IN bu s-roves] Q Specification forming part of Letters Patent No. 199,456, dated January 22, 1878 application filed r November 23,1877. 1 i i To all 'w holn it camera I l Be it known that I, PEARL Mnn'rimof Medford, in the'county of Middlesex and State of Massachusetts, have inventedcertain Improve ments in Stoves for Burning Crude Unrefined Hydrocarbon and other Oils, of which thelfollowing is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which Figure 1 is a perspective view of an oil-stove constructed in accordance with my invention, and removed from its casing. Fig. 2 is a vertical section through the center of the same, inclosed within its casing. Fig. 3 is a plan of the stove detached from the casing, the wicks being removed; Fig. 4, perspective View of one of the wick-holders which I employ, and Fig. 5 sectional detail.

-My present invention has for its object to provide a stove for burning crude unrefined hydrocarbon or other oils; and myinvention consists in a fire-pot having two or more inclined grooved sides, provided with one i or more continuous or separate wicks of asbestus or other suitable material, the wick or wicks of the fire-pot being supplied with oil from an oil-receptacle located near it, or in any other suitable manner, the fire-pot and oil-receptacle being preferably connected in the same apparatus, and inclosed, or not, in a casing, by which construction and arrangement an extended wick-burning surface is presented, and the heating capacity of the stove increased.

To enable others skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, A represents my improved stove for burning crude hydrocarbon or other oils. This stove consists of an oilreceptacle, (1, of rectangular form, located near a rectangular fire-pot, b, a narrow space, 0, intervening between them, in order that the fire may not unduly heat the contents of the receptacle a, the fire-pot and the oil-receptacle both rising from a common base, d, and communicating with each other by a passage, 0, formed therein. This passage is provided with a tube, 6, the portion of which contiguous to the oil-receptacle is formed of metal, while the portion the fire-pot is of glass, on

account of its being a non-conductor of heat, the metal portion of the tube being, provided with a;stop;-.coc k,f, which may beopened or closediby operating handle, g, extending up therefrom into the space c. .The front and rear sides h i of the interior of the fire-pot are in cl'ined from its topdown toward each :other, the lower ends of the inclined sides beingseparated by a narrow space,k, extending trans versely across the fire-pot, which space is enlarged below, and extends under the inclined sides, being formed in cross-section as shown in Fig: 2, the center of the space it being located directly over the outlet of the tube 6, through which the oil in the receptacle a is conducted to the fire-pot. Each of the inclined sides hi is provided with one or more grooves or recesses, l, the bottoms of which incline down to the outsides of the space k, and within these grooves or recesses are placed wicks m, composed preferably of cotton, hemp, linen, jute, or other suitable fibrous material, covered with a layer of asbestus; but the entire wick may be composed of asbestus or other suitable material, if desired.

Each wick is laid within a casing or holder, n, of sheet metal, of the form seen in Fig. 4, fitting snugly within its groove Z, by which arrangement the oil, as it flows from the receptacle a through the tube 0 into the space is in the fire-pot, is taken up by the wicks m, the flame from the two opposite inclined sides uniting, and being drawn upward in the direction of the flue or aperture 12 in a suitable casing, B, adapted to the shape of the stove, and provided with a cover extending over the oil-receptacle, the unconsumed smoke and gases passing up the chimney or other flue.

The top of the fire-pot is provided with a hinged metal plate, 0, which is thrown back, as seen in Fig. 2, when a fire is required, the

plate, when closed, serving as an extinguisher to put out the fire when not wanted, the rear portion of the plate being provided with perforations, to allow of the escape of the smoke and gas after the flame is extinguished.

Instead of placing separate and independent wicks within metal casings or holders n, the wicks may be laid up directly within the inclined grooves lof the fire-pot, the holders being dispensed with; but I find itmore con-- venient .to employ them, and the wicks may;

be made continuous, so that one will occupy the entire area of one or both of the inclined sides of the fire pot, in which latter case a greater amount of burning-surface would be insured, and the degree of the heat be intensi fied.

Instead of a fire-pot having two of its opposite sides inclined and provided with wicks,

as shown, more than two of its interior sides may be inclined and provided with Wicks, and the oil-receptacle may be located to one side of, or above or below, the fire-pot.

The above-described apparatus maybe made of soap-stone, iron, &c., and is specially designed forburning liquid fuel in the shape of heavy unrefined hydrocarbon, vegetable, or an- 1. Afire-pot, b, having two or more inclined grooved sides, provided with one or more continuous or separate wicks of asbestus or other suitable material, in combination with an oilreservoir, substantially as described.

2. The oil-receptacle a, in combination with the fire pot b, having two or more inclined grooved sides, provided with one or more separate or continuous wicks, substantially as and for the purpose set forth. v

3. A sheet or other metal wick-holder, n, in combination with a fire-pot, I), having two or to secure byLetters Patentasan improvement more inclined grooved sides, provided with one or more grooves, l, and an oil-receptacle, as and for the purpose described. v

4. A casing, B, in combination with the firepot 6, having two or more inclined grooved sides, and an oil receptacle, 0, as and for the purpose described. Witness my hand this l5th day of Novem-' ber, 1877.
